Unlike modern squid, they had a hard internal skeleton; in the animal's tail, this formed a bullet-shaped structure called a rostrum. These rostra are the parts found as fossils. When buried in opal-bearing sediments, the organic material was replaced by precious opal over millions of years, creating the extraordinary opal belemnites we find today.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.65 carats\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e Approximately 12 x 4 x 3 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Rectangular bar (belemnite rostrum form)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Natural solid opal, cut from opal belemnite fossil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Australia\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Cut and polished, ready to set or recut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRef:\u003c\/strong\u003e NB17\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cp\u003eEthically sourced.
